impulse registering devices. Among the the operation of astepping magnet 12. Bepurposes for which the arrangements of the \cause of the multiples of three in the relay invention may be particularly useful may be train and in the first selector respec- 5 enumerated that of ascertaining the fretive ly it is seen that if impulses are ap lied quency of current pulses transmitted over for one minute the second selector indian electrical circuit, or for checking or cates directly in impulses per second. A measuring interrupter or ringing machine restoring key K is provided, associated with speeds, or other pur oses in which it is de the selectors, whereby they maybe restored sirable to ascertain t e duration and number to normal. of impulses transmitted over a circuit. The The operation of the arrangement is as arrangements of the invention have the fo'lfollows: An impluse coming in over the lowing advantages: That one final reading line L will operate the relay 1.

A connection will 25 the .figure of which is illustrated a circuit now be established over the contacts and diagram of a referred form of the invenarmature of relay 2 and over the right-hand tion. In the rawingis shown a circuit L armature and contact of relay 3 and the over which are transmitted electrical imbreak contact of relay 4, through the windpulses. These impulses, through the opering of relay 4 to battery 14 and ground, ation of the relay 1, will operate an impulse thereby operating relay 4, which will lock translating relay 2, which in operating will up over its left-hand armature and make cause the first of a train of three relays, 3, contact. The third incoming impulse from 4 and 5 to pull up. This latter relay, in the line L will, in like manner, momenoperating, locks up in operated condition tarily operate relay 2 and allow a circuit to.

in the train-of three. This relay, in operon operating, will short circuit the battery ating, will cause the operation of a step- 14 with respect to the relays 3, 4-and 5 and ping magnet 6. The stepping magnet 6 conallow them to release. It will also appl trols the operation of a selector switch 7 ground to conductor 15 and thence throug having two sets of arms 8 and 8 and 9and the windin of the stepping magnet 6 to 45 9. The operation of the last relay of the battery an ground. This will cause the train of three in operating the stepping magstepping magnet 6 to operate. The operanet will cause the selectorswitch 7 to move iOnof magnet 6 will in a wellno 1- its arms one ste and in addition will trip ner release mechanism which will allow the ed the chain 0 three relays so that they arms of selector 7 to move ahead one step. are ready to receive the next 1m ulse. When The arm 8 of selector 7 will now rest on segthe first selector has advance 20 steps t ment 10 and connect a ground to the con- 10! automatically advances itself to the zero /ductor leading to the. stepping magnet 12 position in readinessfor the next set of and battery, thereby maintaining the stepthree pulses, and at the same time will adping magnet 12 in operated position so that the arms ofthe second selector 13 will not be operated under these conditions. The next three incoming impulses will in like manner operate the train of relays 3, 4 and 5 and cause the stepping magnet 6 to move the arms of selector 7 ahead another step. This operation will be repeated until the arm of the selector, such as 9, shallhave reached the twentieth step. At this point a ground will be applied from the twentieth step to the arm of the selector and thence over conductor 16, contact and armature of the step ping magnet 6, through the winding of sa d magnet to battery and ground. This W1ll cause the stepping magnet 6 to operate at this instant so that the arms of the selector will automatically be advanced a step to 21. The ground applied from 21 will now advance the arm to the zero position again. When the arm 8, upon this operation of being restored to zero position, leaves the segment 10, the circuit heretofore mentioned through the stepping magnet 12 Wlll be broken and the ste ping ma et 12 will release and advance 51c arm 0 the selector 13 one position. Accordingly, each set of three impulses coming in over the line L will operate the selector 7 one step. When the selector 7 has operated 20 steps the selector 13 will, as has been pointed out, be operated one step. Accordingly, because of the multiples of three in the relay chain 3, 4 and 5, and 20 in the selector 7, it is seen that an application of impulses to the line for one minute will give a direct reading on the steps of the selector 13 of the impulses per second. It should be noted that the contact arrangement of the impulse translating relay 2 acts in a way so as to translate the incomin pulses which may be of difi'erent length as not to cause false counting on the part of the relay chain. The restoring key K, which is provided, will, by applying ground to the contact steps of the selectors, cause the operation of the stepping magnets 6 and 12 to cause the selector switches to return to the zero position.

While the invention has been disclosed in certain specific forms which are deemed desirable, and though reference has been made to the multiples 3 and 20, it is to be understood that the invention is not so limited, but that it is capable of embodiment in many other widely varied arrangements without departing from the spirit of the invention as defined by the appended claims.

What is claimed is:

1. An indicating device comprising an imtions of said impulse translating relay, the

operation of said relays in said train being dependent upon each other, a selector switch, means controlled by the operation of the last relay of said train of relays for releasing all of said train of relays and for moving said selector switch one step, a second selector switch, and means controlled by said first selector switch after it has moved a predetermined number of steps for operating said second selector switch.

3. An indicating device comprisin an impulse translatin relay, a train 0 relays operated successively by successive operations of said im ulse translating relay, the operation of said relays in said train being dependent upon each other, a plurality of selector switches, means controlled by the operation of the last relay of said train of relays for releasing all of said train of relays and for moving one of said selector switches one step, and means controlled by said last mentioned selector switch after it has been moved a predetermined number of steps for restoring it to normal position and for operating Other of said selector switches.

4. An indicating device comprisin an impulse translating relay, a train of t ree reg lays operated successively by successive operations of said impulse translating rela the operation of said relays in said train being dependent upon each other, a selector switch having twenty steps, means controlled by the operation of the last relay of said train of re ays for moving said selector switch one step, a second selector switch, means controlled by said first selector switch after it has moved twenty steps for moving said second selector switch one step and for restoring itself to normal position, and a switching mechanism associated with both of said selector switches for restoring them to normal position.

In testimony whereof, we have signed our names to this specification this 8th day of July, 1924:.
